CHE 598 Seminar: Electrochemical Gas Sensor Systems

About the event

SPEAKER:
Dr. Praveen Sekhar, Associate Professor, School of Engineering and Computer Science, WSU-Vancouver

ABSTRACT:
Ubiquitous sensors are becoming an integral part of Internet of Things (IoT) applications, and progress in this domain has witnessed exponential growth. The promise is that everyone and everything will be connected via wireless data collection, and services like healthcare will be brought to everyone, everywhere, anytime, for virtually any need. In particular, the field of gas sensors has seen technological advancements for industrial, environmental, national security and energy security applications. This talk will focus on high temperature and room temperature applications of electrochemical gas sensors. Further, the talk will discuss the emergence of flexible gas sensors. Electrochemical modality is ideal to implement flexible gas sensors as (a) electrodes can be miniaturized and easily fabricated onto the substrate (b) portable and flexible potentiostats can be implemented for transduction, and (c) device arrays can be fabricated lending to high density manufacturing.
